HTML & PHP Camera Capture

I have a page that im designing to be used on smartphones. I have added an input to a html form to capture a image from the camera. When clicked on the upload file button it asks take photo or upload from gallery which is spot on. If you select from gallery it works fine and the image is uploaded to the webserver, but if the camera is selected nothing comes up. Is there a different line of code required to determine where the image is coming from?
